javascript typescript sorting key

Answer №1

To arrange the elements in an array, you can utilize the built-in sort method. In order to specify the sorting criteria, you must provide a callback function to the sort method.


var a = /* your array */ ;
a.sort(function(x, y) { return x.name <= y.name ? -1 : 1; });

The callback function takes two parameters, which represent elements of the array, and it should return a negative value if x < y, 0 if x == y, and a positive value if x > y. For more information, refer to this resource. In this case, we are comparing strings based on lexicographical order and returning either -1 or 1.

This sorting technique is applicable in JavaScript, and there are no TypeScript-specific considerations in this scenario.
